Like image shows, I used UIBarbuttonItem as rightBarButtonItem, what I want to do is just change rightBarButton's title when I select a picture or deselect a picture, so I used code like this:
[self.rightBarButton setTitle:[NSString stringWithFormat:#"完成（%#/%#）",#(_selectedAssets.count),#(self.maxPicturesNum)]];
but the barbutton will show shin when its text changed, I try to use UIButton instead of UIBarButtonItem, and shin effect disappear indeed, but UIButton will be close to right bounds far, can you help me?
You can create UIButton and assign it to your rightBarButton
UIButton *rightButton = [[UIButton alloc] initWithFrame:someFrame];
[rightButton setBackgroundImage:someImage forState:UIControlStateNormal];
[rightButton addTarget:self action:#selector(back:) forControlEvents:UIControlEventTouchUpInside];
rightButton.titleLabel.text = [NSString stringWithFormat:#"完成（%#/%#）",#(_selectedAssets.count),#(self.maxPicturesNum)];
rightButton.titleLabel.font = someFont;
UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightButton];
self.rightBarButton = rightBarButtonItem;
And while updating label use rightButton.titleLabel.text
For Adjusting label use this:
- (void)setTitlePositionAdjustment:(UIOffset)adjustment
forBarMetrics:(UIBarMetrics)barMetrics
Finally,I do like this:
- (void)loadRightButtonItem{
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(30, 0, 120, 40);
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentRight;
[button setTitle:#"完成（0/9）" forState:UIControlStateNormal];
button.tintColor = [UIColor whiteColor];
[button setTitleShadowColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
// [button setTitleColor:[self.buttonFolder titleColorForState:UIControlStateHighlighted] forState:UIControlStateHighlighted];
[button addTarget:self action:#selector(onFinishClicked:) forControlEvents:UIControlEventTouchUpInside];
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 135, 40)];
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:view];
[view addSubview:button];
self.navigationItem.rightBarButtonItem = item;
_rightBarButton = button;
}
It cancel the shin effect.
thanks to #RoHaN,your idea did great inspired me.

I'm trying to add a centered button in my navbar header, confused as to how I can do it
- (void)viewDidLoad {
[super viewDidLoad];
UIImage *meImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:#"%#/me.png", kSelfBundlePath]];
UIBarButtonItem *meButton = [[UIBarButtonItem alloc] initWithImage:meImage style:UIBarButtonItemStylePlain target:self action:#selector(twitterButton)];
[self.titleView //i read this can be used to like set it but i havent been able to figure it out
help would be appreciated, pretty new
check this code
UIView *container = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
container.backgroundColor = [UIColor clearColor];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0, 0, 44, 44)];
[btn setBackgroundImage:[UIImage imageNamed:#"button0.png"] forState:UIControlStateNormal];
[btn addTarget:self action:#selector(btnAction:) forControlEvents:UIControlEventTouchUpInside];
[btn setShowsTouchWhenHighlighted:YES];
[buttonContainer addSubview:button0];
//add your spacer images and button1 and button2...
self.navigationItem.titleView = container;
You can try like this way
UIView *topView = [[UIView alloc]initWithFrame:CGRectZero];
UIButton * button = [[UIButton alloc]initWithFrame:CGRectZero];
[button addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"Title here" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button sizeToFit];
[topView addSubview:button];
[topView sizeToFit];
self.navigationItem.titleView = topView;
-(void)buttonAction:(Id) sender {
NSLog(#"button clicked");
}
I think its pretty straight, you can use titleView property of UINavigationItem :
-(void)addCenterButton {
UIImage *meImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:#"%#/me.png", kSelfBundlePath]];
UIButton *button = [[UIButton alloc] initWithFrame::CGRectMake(0, 0, 40, 20)];
[button setImage:meImage forState:UIControlStateNormal];
[button addTarget:self action:#selector(twitterButton) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.titleView = button;
}
I have added a toolbar and then added 3 buttons to it programmatically. However, the 3 buttons are all cluttered to a corner. What i want to do is to have even spaces between the 3 buttons so the UI look decent.
How can I do this?
UIButton *button = [UIButton buttonWithType:100];
[button addTarget:self action:#selector(hideGender:) forControlEvents:UIControlEventTouchUpInside];
[button setImage:[UIImage imageNamed:#"img"] forState:UIControlStateNormal];
[button setTitle:#"Images" forState:UIControlStateNormal];
button.imageEdgeInsets= UIEdgeInsetsMake(0.0, 0.0, 0, 50);
button.tag=0;
UIButton *button2 = [UIButton buttonWithType:100];
[button2 addTarget:self action:#selector(hideSchool:) forControlEvents:UIControlEventTouchUpInside];
button2.tag=2;
button2.imageEdgeInsets= UIEdgeInsetsMake(0.0, 0.0, 0, 50);
[button2 setImage:[UIImage imageNamed:#"img22"] forState:UIControlStateNormal];
UIButton *button3 = [UIButton buttonWithType:100];
[button3 addTarget:self action:#selector(hideCar:) forControlEvents:UIControlEventTouchUpInside];
button.tag=3;
button3.imageEdgeInsets= UIEdgeInsetsMake(0.0, 0.0, 0,50);
[button3 setImage:[UIImage imageNamed:#"img3"] forState:UIControlStateNormal];
UIBarButtonItem *barButtonItem0 = [[UIBarButtonItem alloc] initWithCustomView:button] ;
UIBarButtonItem *barButtonItem2 = [[UIBarButtonItem alloc] initWithCustomView:button2] ;
UIBarButtonItem *barButtonItem3 = [[UIBarButtonItem alloc] initWithCustomView:button3] ;
UPDATE: I want to use only UIbutton
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setBackgroundImage:[UIImage imageNamed:#"image.png"] forState:UIControlStateNormal];
[btn addTarget:self action:#selector(action:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barBackButton = [[UIBarButtonItem alloc] initWithCustomView:btn];
[toolBar setItems:[NSArray arrayWithObject:barBackButton]];
Now in setItems set the array of buttons. Suppose you want to put three buttons, then width of each button will be screenWidth/3 and text will be center-aligned. In this way, there is no over-riding of button.
I am trying to use following code in my viewDidLoad method to add two UIBarButtonItems to the left side of the navigation bar, but only the second button is shown:
//nav bar buttons
UIView* leftButtonView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 40, 40)];
UIButton* leftButton = [UIButton buttonWithType:UIButtonTypeSystem];
leftButton.backgroundColor = [UIColor clearColor];
leftButton.frame = leftButtonView.frame;
[leftButton setImage:[UIImage imageNamed:#"toTop"] forState:UIControlStateNormal];
[leftButton setTitle:#"" forState:UIControlStateNormal];
leftButton.tintColor = [UIColor redColor]; //Your desired color.
leftButton.autoresizesSubviews = YES;
leftButton.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin;
[leftButton addTarget:self action:#selector(toTop:) forControlEvents:UIControlEventTouchUpInside];
UIView* leftButtonView2 = [[UIView alloc]initWithFrame:CGRectMake(85, 0, 40, 40)];
UIButton* leftButton2 = [UIButton buttonWithType:UIButtonTypeSystem];
leftButton2.backgroundColor = [UIColor clearColor];
leftButton2.frame = leftButtonView.frame;
[leftButton2 setImage:[UIImage imageNamed:#"toSectionTop"] forState:UIControlStateNormal];
[leftButton2 setTitle:#"" forState:UIControlStateNormal];
leftButton2.tintColor = [UIColor redColor]; //Your desired color.
leftButton2.autoresizesSubviews = YES;
leftButton2.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin;
[leftButton2 addTarget:self action:#selector(toTop:) forControlEvents:UIControlEventTouchUpInside];
[leftButtonView addSubview:leftButton];
[leftButtonView2 addSubview:leftButton2];
UIBarButtonItem* leftBarButton = [[UIBarButtonItem alloc]initWithCustomView:leftButtonView];
UIBarButtonItem* leftBarButton2 = [[UIBarButtonItem alloc]initWithCustomView:leftButtonView2];
self.navigationItem.leftBarButtonItem = leftBarButton;
self.navigationItem.leftBarButtonItem = leftBarButton2;
Any help is welcome. Thank you
You're setting the same property twice so the second setting replaces the first. Try:
self.navigationItem.leftBarButtonItems = #[ leftBarButton, leftBarButton2 ];
Note this is setting leftBarButtonItem*s*, which takes an array of bar buttons.
Also, you shouldn't need the container views, they add no value. Buttons are views so you can use them directly. Setting the frame origin of the view may also cause you issues.
I want to add a back arrow to a leftBarButtonItem, to make it appear visually as if it was a regular back button, although it's functionality is slightly different.
Is there a way to do this?
You can use custom button and hide the back button if you are using navigation controller.
To hide back button use this:
self.navigationItem.hidesBackButton = YES;
And for Custom Button:
UIButton * customButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customButton setBackgroundColor:[UIColor colorWithRed:197.0/255.0 green:190.0/255.0 blue:157.0/255.0 alpha:1.0]];
[customButton setTitle:#"Do Something" forState:UIControlStateNormal];
customButton.titleLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size:11.0f];
[customButton.layer setCornerRadius:3.0f];
[customButton.layer setMasksToBounds:YES];
[customButton.layer setBorderWidth:1.0f];
[customButton.layer setBorderColor: [[UIColor grayColor] CGColor]];
customButton.frame=CGRectMake(0.0, 100.0, 50.0, 25.0);
[customButton addTarget:self action:#selector(customMethod:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem * customItem = [[UIBarButtonItem alloc] initWithCustomView:customButton];
customItem.tintColor=[UIColor blackColor];
self.navigationItem.leftBarButtonItem = customItem;
This will work for you.
Happy Coding
If you are using UINavigationController and then push new viewcontroller it will automatically show back button.
If you are Not Using UINavigationController than
Use Custom UIButton for that with back image
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
backButton.frame = CGRectMake(0, 0, 48, 37);
[backButton addTarget:self action:#selector(backButtonTapped) forControlEvents:UIControlEventTouchUpInside];
backButton.showsTouchWhenHighlighted = YES;
UIImage *backButtonImage = [UIImage imageNamed:#"back-button.png"];
[backButton setImage:backButtonImage forState:UIControlStateNormal];
backButton.imageEdgeInsets = UIEdgeInsetsMake(10, 10, 10, 10);
UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
self.navigationItem.leftBarButtonItem = backBarButtonItem;
You can change the value for the frame and the imageEdgeInsets as per your requirements.

Update - One Possible Solution
Based on answer given by Alexander Merchi in this post (UIBarButtonItem Custom view in UINavigationBar), a solution is found. But still don't know how to change the position of the image properly.
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0, 0, 28.0f, 28.0f)]; // 28 points is the width or height of the button image
[btn setBackgroundImage:[UIImage imageNamed:#"button.png"] forState:UIControlStateNormal];
[btn addTarget:self action:#selector(onClickMenuButton) forControlEvents:UIControlEventTouchUpInside];
btnMenu = [[UIBarButtonItem alloc] initWithCustomView:btn];
Original Post
In iOS 6, the goal is like this:
while current result is like this:
My code is
btnMenu = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"button.png"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(onClickMenuButton)];
button.png is this the white circle with white three bars inside and a tranparent background.
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeCustom];
rightButton.frame = CGRectMake(0, 0, 30, 30);
[rightButton setImage:[UIImage imageNamed:#"Button-normal"] forState:UIControlStateNormal];
[rightButton setImage:[UIImage imageNamed:#"logout-hover"] forState:UIControlStateHighlighted];
[rightButton addTarget:self action:#selector(logOut) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightButton];
self.navigationItem.leftBarButtonItem = rightBarButtonItem;
I am accomplishing it by
UIImageView *uView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"btn_back_ontouch_scr11.png"]];
UIButton *leftButton = [UIButton buttonWithType:UIButtonTypeCustom];
leftButton.bounds = CGRectMake( 0, 0, uView.frame.size.width, uView.frame.size.height );
[leftButton setImage:uView.image forState:UIControlStateHighlighted];
[leftButton setImage:[UIImage imageNamed:#"btn_back_normal_scr11.png"]forState:UIControlStateNormal];
[leftButton addTarget:self.navigationController action:#selector(popViewControllerAnimated:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *aButton = [[UIBarButtonItem alloc] initWithCustomView:leftButton];
self.scrollView.indicatorStyle=UIScrollViewIndicatorStyleWhite;
self.navigationItem.leftBarButtonItem = aButton;
self.navigationItem.hidesBackButton = YES;
This should work.
